Granulation drying equipment is usually used in the granulation production process. Granulation drying equipment is a kind of drying equipment that produces products after the particle size requirements are achieved by fluidizing, dust removal, atomization, solidification and other treatments on the materials. It is widely used in chemical, pharmaceutical, food and other industries. By heating, the moisture in the material (generally refers to water or other volatile liquid components) is vaporized and escaped to obtain solid materials with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing.
